5 0

Newton's First law states the Law of Inertia. The Law of Inertia says that an object at rest must stay at rest unless an applied force is acted upon it. Roller coasters run by this law, they must be pulled by a motor to get started. ... At ride will continue until another opposite force is applied to the ride, the breaks.

Keith_Richards [23]

Answer:

Density =0.74 g/cm^{3}

Explanation:

Step 1: Formula

 Density=\frac{Mass}{Volume}

Step 2: Data

m=278 g

v=375 cm^{3}

Step 3:Solve

d= \frac{278}{375} g/cm^{3}

d=0.74 g/cm^{3}

A star with a large luminosity would have a relatively _____ absolute magnitude.
Mademuasel [1]
A star with large luminosity would have a relatively low absolute magnitude. Absolute magnitude is a number that tells how bright a star is from the Earth. However, this scale is backwards and logarithmic, so having a large absolute magnitude value means that the star is faint.

You wish to buy a motor that will be used to lift a30-kg bundle of shingles from the ground to the roof of a house. The shingles
hodyreva [135]

Answer:

the minimum value of torque is 101.7 N-m.

Explanation:

Given that,

Mass of bundle of shingles, m = 30 kg

Upward acceleration of the shingles,

The radius of the motor of the pulley, r = 0.3 m

Let T is the tension acting on the shingles when it is lifted up. It can be calculated as :

T-mg=ma

T=m(g+a)

T=10\times (9.8+1.5)\\T = 113 N

Let \tau is the minimum torque that the motor must be able to provide. It is given by :

\tau=r\times T\tau=0.3\times 339\tau=101.7\ N-m

the minimum value of torque is 101.7 N-m.
